Connection to supplementary coil in SHW hot water tank
The SHW container is equipped as standard with a supplementary coil with a length of 8.5m.
The supplementary coil can be connected to a solar panel with external solar heating control (not Nilan supply), or other heat source,
which contributes to heating the domestic water.
Connecting to DHW hot water
If the demand for domestic hot water exceeds the capacity of the heat pump in the Compact P2 unit, AIR can be connected to the solar
coil in the DHW tank. It will then help heat the domestic hot water.
ATTENTION
If another container with a shorter supplementary coil is connected, the compressor output in the hot water production
must be reduced. See the Software manual.
